Summary:
Seismic data have a key role to play in exploration and field development, enabling reservoir delineation and characterization as well as reducing drilling risks. We discuss recent seismic technology developments and show how they have provided new insights into subsurface geology, reservoir properties, and drilling hazards. One of the most significant advances in recent years has been in earth model building and imaging and has been driven by a combination of new algorithms such as full-waveform inversion (FWI) and sophisticated imaging techniques, and an increase in experience and wide-spread usage of those technologies, which can significantly improve interpretation for both newly acquired data and heritage conventional data. We show examples of seismic data processed with the latest technology, including earth model building with FWI compensation of variable illumination with least-squares migration. These advanced technologies allow us to overcome very complex imaging and geological challenges and enable achieving a wide range of subsurface imaging objectives across the E&P life cycle.
